MBAC Reports NI 43-101 Resource Estimate for World Class Araxá Rare Earth Oxide/Niobium/Phosphate Deposit

Dec 06, 2011

OTC Disclosure News Service

Toronto, ONT, Canada –

Toronto, Ontario, December 6, 2011, MBAC Fertilizer Corp. (“MBAC” or the “Company”) (TSX:MBC and OTCQX:MBCFF) is very pleased to report a National Instrument 43-101 (“NI 43-101”) compliant independent inferred mineral resource estimate for the rare earths oxides at the Company’s 100% owned Araxá Rare Earth Oxide (“REO”)-Niobium-Phosphate Project (the “Araxá Project” or the “Project”) located in the western part of Minas Gerais State, Brazil. The inferred mineral resource estimate is based on 35 diamond drill holes for 3,485 metres, 68 auger holes for 381 metres and 43 pits for 436 metres.


Highlights of Mineral Resource Estimate:

·         The inferred mineral resource estimate comprises 2.7M tonnes with an average total REO (“TREO”) content of 8.39% (using a 6% TREO cut-off) and an average of 1.4% Nb2O5 and 9.9% P2O5

·         Heavy rare earth oxides (“HREO”) represent 2.22% of the TREO based on the recent MBAC assays.

·         These grades place the Araxá deposit as one of the highest grade REO deposits in the world.

·         An additional exploration target has been defined by existing wide spaced diamond drill holes consisting of between 28M tonnes and 34M tonnes at between 4% TREO and 6% TREO.

Antenor Silva, President and CEO, stated “This resource estimate places Araxá as one of the highest grade REO deposits in the world.  The monazite mineral found at the property is one of the typical sources of rare earths and should gives us confidence that the material should be able to be processed into the various REO concentrates. We are currently undertaking metallurgical tests to confirm the ability to produce the REO concentrates.  The deposit is situated in the fertilizer cluster of Brazil in Minas Gerais State which has excellent infrastructure. We continue to see great interest from companies looking for off-take agreements not only for the rare earth elements but for the niobium as well.  It is important to remember that the rare earth niobium deposit is sitting above what we believe to be a very significant phosphate deposit.  Our next milestone is to complete a preliminary economic assessment for the rare earth oxides which is expected in the first quarter of 2012.” 

The Araxá Project

The Project consists of four tenements covering 214 hectares. The Barreiro carbonatite containing the Araxá REO is also the host rock to the Brazilian Company Companhia Brasileira de Metalurgia e Mineração’s (“CBMM”) massive niobium mine which currently supplies approximately 85% of the world’s niobium each year. Historical exploration from the Araxá Project has led to the discovery of significant REO, phosphate and niobium mineralization. Phosphate occurrences in the carbonatite were first discovered in the early 1950’s and the tenement areas optioned to MBAC have been explored over the past 50 years by DNPM/Geosol, IPR, CBMM, Rhône-Poulenc and Extramil (including a joint venture partner – CIF).

Summary of the Mineral Resource Estimate

The Araxá inferred mineral resource estimate is based on 35 diamond holes (3,485m), 68 auger holes (381m) and 43 pits (436m) drilled at a spacing of approximately 40m by 40m.  Only data received as at December 1, 2011 has been used in this estimate.  MBAC has an ongoing 3,000m infill and extensional diamond drill hole program underway but no results are available from this phase of drilling.

The mineral resource estimate is focussed on an area of 480m by 240m which hosts the majority of the 40m spaced drilling.  Other wide spaced drilling has not been included as the 200m spacing is too wide to allow sufficient geological confidence.  The majority of sample data was completed in mineralization at between 10m to 50m in depth although there are limited diamond holes deeper than 40m vertical depth and as such the footwall limit to the mineralization is poorly defined.  All mineralization is contained within saprolitic material and has been interpolated as a single mineralized horizontal domain.  The REO mineralization remains open in all directions.

The historical exploration data was assessed for its precision and accuracy where possible.  Only the Extramil series of diamond core holes was available to resample but these holes had no immediate influence on the current inferred resource area.  The majority of the historical samples have hard copy assay certificates available and have been analyzed in respected international laboratories. In addition, MBAC completed 36 auger holes which were analyzed at SGS Geosol laboratory.  The results to these auger holes were compared to historical holes drilled within 15 metres and moderate precision was found.  The MBAC auger holes were submitted with two (2) Geostats Pty Ltd certified REO standards and were returned acceptable accuracy.

The mineral resource has been classified by qualified person Beau Nicholls (BSc (Geo) MAIG) principal consulting geologist for Amazon Geoservices Ltda (“Amazon Geoservices”) in accordance with NI 43-101 effective as of December 2, 2011.  The inferred mineral resource estimate comprises of 2.7M tonnes with an average TREO content of 8.39% (using a 6% TREO cut-off) and an average of 1.41% Nb2O5 and 9.91% P2O5


Mineral resources are not mineral reserves and do not have demonstrated economic viability

Appropriate rounding has been applied to the table 1


TREO includes La2O3, Ce2O3, PR2O3, Nd2O3, SM2O3, Eu2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3, Lu2O3 and Y2O3

LREO (97.78% of TREO)  includes La2O3, Ce2O3, Pr2O3 ,Nd2O3 andSM2O3,

HREO (2.22% of TREO) includes Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Eu2O3 and Gd2O3 and Lu2O3. 

**Only 4.5 % of the database was analyzed for TREO. A factor of 1.27 was determined by analysis of this data and applied to the sum of CeO2 + La2O3 +Y2O3 which was analysed for all holes.


Future Exploration Target


An exploration target has been defined by existing 200m to 400m wide spaced diamond drill holes with between 28Mt and 34Mt at between 4% TREO and 6% TREO. It is important to point out that the potential quantity and grade of the exploration target is conceptual in nature. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the determination of a mineral resource.


MBAC is currently drilling the deposit at 40 metre spacing in the REO mineralized area aiming to define measured and indicated resources. The samples are being analyzed via ICP-MS at SGS Geosol laboratory located in Belo Horizonte, Brazil.


Surface topography has been completed utilizing a total station to an accuracy of +/-10cm.

The majority of the exploration data is historical, however Amazon Geoservices has completed a site visit and validated the drill hole positions and geology in the field and have reviewed the available diamond core which is stored in Belo Horizonte. Due diligence grab samples have been taken in the field by Amazon Geoservices and a resampling umpire program for the available diamond drill holes duplicate samples and auger sampling was submitted to SGS Geosol laboratories along with appropriate QAQC.  The full suite of REO has not been systematically analyzed by historic explorers.  A factor of 1.27 has been determined by MBAC and Extramil assays to allow a global resource estimate to be undertaken at this stage of exploration.  Current MBAC drilling will analyze the full suite of rare earth elements.
